An ethnographic study of Irish music sessions in pubs elaborates the collaborative work involved in making traditional music. Central to this distinctive achievement is the sequencing of tunes so that they hang together and combine to form discrete "sets", which rely on a shared knowledge of musical repertoires. Our study shows how musicians develop this(More)
An ethnographic study uncovers the work of nightclub DJs, which extends far beyond the act of mixing tracks to also encompass collecting music, preparing for performances, and promotion and networking. We reveal how DJs value vinyl and digital formats in different ways, acquire music through 'crate digging', prepare physical and digital crates of music(More)
Single drop microextraction (SDME) can be in-line coupled with capillary electrophoresis by attaching a drop to the tip of a capillary. With a 2-layer drop comprised of an aqueous basic acceptor phase covered with a thin organic layer, acidic analytes in an aqueous acidic donor phase can be extracted into the organic layer and then back-extracted into the(More)
A simple, fast, highly efficient and direct method using ultra-performance liquid chromatography coupled to mass spectrometry has been established for the simultaneous separation, identification and quantitation of a few saturated and unsaturated fatty acids in olive oils from various countries. No sample pretreatment techniques were employed such as(More)
Ultra performance liquid chromatography coupled to mass spectrometry was used for the simultaneous separation and determination of reducing monosaccharides (fructose and glucose), a non-reducing disaccharide (sucrose) and oligosaccharides (kestose and nystose) in HILIC mode. The chromatographic separation of all saccharides was performed on a BEH amide(More)
In order to analyze amino acids sensitively without derivatization, we have developed carrier-mediated single drop microextraction (SDME). Nonane-1-sulfonic acid was added to an acidic sample donor solution as a carrier to form neutral ion pair complexes with amino acids. The ion pair complexes were extracted to the organic phase, covering a drop of an(More)
